Tennessee boat lettering guide

Tennessee Boat Registration Number Requirements

A clear guide to Tennessee boat registration number size, placement, spacing, color contrast, and validation decal positioning.

Where Tennessee Boat Numbers Go

Display the TN number on both sides of the bow and read it from left to right. The number should remain visible, legible, and free from other markings that could make it hard to identify.

Core Display Requirements

  • Use the state prefix TN exactly as assigned on your registration.
  • Use plain block characters at least three inches high.
  • Read the complete number from left to right.
  • Use a strongly contrasting color against the hull or background panel.
  • Separate letter and number groups with hyphens or spaces equal to a character width.

Validation Decal Placement

Display the current validation decals with the registration numbers as directed by TWRA. Install decals only after cleaning and drying the surface, and keep them visible for inspection.
